pub struct ObservationalIslamicMarker;

Marker type for observational islamic calendar, for use with IslamicBasedMarker

Trait Implementations

impl Clone for ObservationalIslamicMarker

fn clone(&self) -> ObservationalIslamicMarker

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ObservationalIslamicMarker

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for ObservationalIslamicMarker

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl IslamicBasedMarker for ObservationalIslamicMarker

const EPOCH: RataDie = FIXED_ISLAMIC_EPOCH_FRIDAY

The epoch of the calendar. Different calendars use a different epoch (Thu or Fri) due to disagreement on the exact date of Mohammed’s migration to Mecca.

const DEBUG_NAME: &'static str = "ObservationalIslamic"

The name of the calendar for debugging.

const HAS_353_DAY_YEARS: bool = true

Whether this calendar is known to have 353-day years. This is probably a bug; see https://github.com/unicode-org/icu4x/issues/4930

fn fixed_from_islamic(year: i32, month: u8, day: u8) -> RataDie

Convert an islamic date in this calendar to a R.D.

fn islamic_from_fixed(date: RataDie) -> (i32, u8, u8)

Convert an R.D. To an islamic date in this calendar

fn mean_synodic_ny(extended_year: i32) -> RataDie

Given the extended year, calculate the approximate new year using the mean synodic month

fn approximate_islamic_from_fixed(date: RataDie) -> i32

Given an iso date, calculate the approximate islamic year it corresponds to (for quick cache lookup)

fn month_lengths_for_year(extended_year: i32, ny: RataDie) -> [bool; 12]

Given an extended year, calculate whether each month is 29 or 30 days long

impl PartialEq for ObservationalIslamicMarker

fn eq(&self, other: &ObservationalIslamicMarker) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
